Seach results in zero records?

[Archibald Strohalm]

Anybody seen this before?

We're running a fm server 8 v3 on win2000 server with about 100 clients (FM8 on WinXP Prof).

Every now and then (say once every two weeks) every search from every client on every unindexable calculated field returns zero records while we know it should return something.

When we restart de server, everything seems to work again. It's a mistery...

Any help would be very much welcome.
